Application tiled March 13, 1908. Serial No. 529,923.

vTo all whom it may concern:

i means for locking dump cars, and conteur plates the mounting of the lock upon the undcrframe construction of the car, preferably one lock on each side thereof adjacent the end of the underfraine construction; the construction of the lock renders it possible, upon releasing the lock upon one side of the car. to tilt the car towards the opposite side without manipulating the lock on that side before the dumping takes place:wlien the car is returned to its normal position, the locking means on the side towards which the car was dumped come into play to prevent the car from passing the horizontal line of its normal position, while the lock on the opposite side of the Icar which was released again assumes the locking position.

Our invention further contemplates a car lock constructed so as to Vbe operated by the devices which tilt the car, so that the operation of said devices will release the lock desired, and at the salme time said devices' will cause the car to be dumped; when the car is righted the locking means are thereby restored to their normal condition and will retain the car in its normal position until a subse uent dumping o eration is begun.

It urther Contemp ates theprovision of similar locking means arranged on each side of the car, and the release of one of said means permits the dumping of the car on the opposite side.

It further contemplates the provision of means for connecting said lock with the dumping devices, for the manipulation of said lock.

It further contemplates the provision of parts and their combinations hereinafter described more fully and included in the claims.

In the drawings which are hereto attached underframe construction at `colistruction will cause the "door to drop car is in its dumped position; Fig. 3 is a side view of the lock and the means connecting the same with the piston: Fig. 4 `is a side view of a cylinder showing the attachment of th'e lock-manipulating means to the piston; Fic. 5 is a view of the link melnber constructed to engage the lock.

In the drawings, 1 is the car body pivotally mounted at upon a pivotshaft, or if preferred, a series of longitudinal pivots arranged beneath the car body, 3 is the bracket arising fro'uftheyunderframe construction 4 upon which the car body is pivoted, 5 and'6 are cylinders containing pistons, one shown at 7, and bearing the piston rod 8 having at its upper end the link construction 9, the piswith the plate 11 mounted centrally of the lower portion of the end of the car body, engaging with the notches 12, 13, 14' and 15, depending upon which piston is actuated, and upon whether the car is to be dumped or righted.

As shown in Fig. 2, the dumping of the car is effected thi'ough the' cylinder on one side of the underframe construction, and is righted through the cylinder on the opposite side. The doors-16 and 17 ofthe car extend longitudinally thereof at each side, and are supported pivotally as shown at 1S upon the` outer end of an arm 19` ivoted at 20; pivotally connected at 21 wit ithe arm 19 is the link 22, which at its lower end is pivotally connected'at 23 with the lateral arm 24, the latter being pivotally mounted upon the It is apparent that the construction on the opposite side of the car is identical. When the car is dumped, as shown -in Fi 2, the arrangement-,of pivoted arms an connecting link, will effect the raising of the door 1T,` andv when the car is righted the arm and link gradually into itsj ro er position at the sider of the car.' Meam hie, ouille-opposite side of the car the link and arm construction will adapt itself to the elevation of that side of, the caigand will be liftedor depressed according as the car body on that side is elel vated or returned to normal position.

Adjacent the end of the car, and preferably mounted rearwardly of the truck is the box like construction indicated at 26 which is `mounted u on and supported from the I immediatelyfupon passing the shoulder 32 center sill of t e car 27. struction is adapted to contain the locking means and the means for manipulating the same, which will now be described.

At each side of the box like construction nd mounted therein upon the bracket 28 is a. rotary lock 29 journaled at 30 to rotate freely, said lock containin the eccentric portion 3l for the purpose ot giving the lock a tendenc to rotate to bring said portion 3l into the ower position, whereby the lock tends constantly to be positioned properly for engagement with the link 22; the shoulder 32 on said lock is adapted to be positioned against the end 33 on the-outer arm 34 of the bent lever 35, when the parts are in their normal position. Said lever 35 is pivoted at 36 beyond its middle point, so that the arm 37 thereof being heavier will-constantly tend to maintain the arm 34 in engagement with the eccentric portion 3l of the lock 29, when the parts are in their unlocked position; the lock 29 is also provided with the second shoulder 38, which, when the shoulder 32 is freed from engagement with the arm 34 will,

when the lock is rotated, engage with the end 33, and prevent the further rotation of the lock in that direction Shoulder 38 is therefore provided as a precaution rather than as a necessity, although inl case of violent opeiation of the car the said shoulder would be called into use as stated.

The lock 29 is notched as shown at 39, the lower face of the notch being provided with the Harige 40. As shown in Fig. 5. the link 22'l is toi-med preferably of parallel members, said members being united at their lower end by the cross piece 41, so that when the car body occupies its normal position, a portion of the lock 29 is positioned between the parallel members of the link 22 and the crosspiece 4l is adapted 'to be in engagement with the upper :tace 42 of the notch 39.

. As the link 22 is lowered on the side of the car towards which it is being dumped, it will ride over the Harige 40 on the rotary lock 29, the flange being wide enough to prevent its entering the space between the parallel members of the link; consequently Vwhen the car is righted and the link 22 resumes its normal position, it will slide upon the outer face of the liange 40 until the cross piece 4l is brought into proper osition for entering the notch 39a. {f the ange 40a were not provided, the cross piece 41 on the link 22 might envave the lock at a point below the notch, andlbebcaught there-l on, thereby preventing the car body from.

This box-like consaid arm 34 will engage therewith and prevent the further downward movement of said shoulder until the lever 37 is again lifted out of its engagement with said lock. The means for effecting this movement of the lever will now be described.

As pointed out above, the piston rod 8 at a point outside of and adjacent onc end of the cylinder is bent laterally, indicated at 10, and upon the bent portion l0 is mounted a plate 43 which extends laterally and has thereon the recessed portion 44 through the walls of which is passed the pivot bolt 45; mounted upon the ivot bolt 45 to oscillate thereon laterally o the car is the latch 46, containing the reinforcin member 47, said latch depending from sai pivot 45 and extending into the box-like construction 26, being admitted thereinto through the opening 48 at the top and extending out through the lower portion thereof, as appears in Fig. 4. Said latch 46 contains .the notch 49 adapted to receive the pin 50 to be guided thereby; the latch is also provided with the face portion 51, the cam portion 52 and the lower face portion 53, all of which portions may ride upon the pin 50 as the latch is being raised. The latch also is provided with the long slot 54 having the curved 9 faces 55 and 56, the cam face 57, the hook portion 58, the latter having the face portion 59, and the cam surface 60. The lever arm 37 carries the stud 61 which is adapted to be received into the long slotted portion 54, the faces of said portion and the hook and its faces, mentioned above, being adapted to ride upon said stud 6l as the latch 46 is being raised or lowered.

Inasmuch as the latch 46 is mounted upon the plate 43 which is rigidly mounted upon the upper end of the piston rod, the latch will be elevated or lowered with the elevation or lowering of said piston rod; therefore, the application of air to the piston will lift said latch, and when the air is cut orf, the pistonbeing retracted by the spring 62, the latch will be lowered therewith. In Fig. 3 are shown the latch and the lever and the rotary lock and the depending link 22 as they appear when the car body is in its normal posit-ion. If the air be applied and the piston be raised, the latch 46 will be lifted, and inasmuch as the latch occupies an inclined position, the face 5l will remain in Contact with the pin 50; when the hook 58 engages with the stud 6l. the arm 37 of the lever 35 will be lifted, thereby disengaging the end 33 of the short arm from the shoulder 32 on the rotary lock. As the piston continues toA rise the link rivisti-action 9 at the outer end of the piston rod. will engage with the notch l2 on the car hocily and will cause the same to be tilted, thereby, through the link 22a, rotating the lock 29, it

' shoulder 32. As the upward movement of the piston continues, cam face 52 of latch 46 i's brought into engagement with the pin 50, thereby giving the latch a latere. move- 'ment and causingtlie hook 58 to bediscugaged from the stud 6l, and the face 53 en: raging with the pin :30. willmaintnin the atcli out of engagement with the stud 61;

" lthe lever is now free to drop to its normal position. thereby bringing theinner face of the arm into eiufageiuent with the curved )oi-tion of the loclc 2t) as shown in Fig.- 2.

he relative position of the various arts' mentioned in connection with the loc are 4clearliv shown in Fig. 2. so far as concernsl the e erated side of the car body; likewise the: position of the parts connected with the lock ou the depressed side is also shown in 'Fie'. L), reference to which shows that the Y latch anithe locking lever occnliv their normal position. while the lock has )een given a rotaiv movrinent downward by the engagement oi the link 22 with the flange 40* of the notch in Said lock. When the car has been dumped, the air is cnt oi from the oierating piston and the latter is retracted y the springGQ, carrying with it the hitch which 1s returned to its normal position. Now if the car be righted, the link 22* in its descent will engage the flange portion l0 upon ,the lock, causing the latter to he. rotated until the car bod)` has reached itsl normal position. whereupon Aitlwill be found that the lock has been rotated to ila position. shown lig. 1, the "cross piece 4,1' on the link 22 being in engagenient with thc face 42 on Athe notch 39 in the lock. and the outer end 33 of the lever :l5 beingv in engagement. with the shoulder 32 on the said lock. Qn the opposite sido of "tlic car the return of the door 1T to its normal position will cause the lower end of the link .2 to hc swung towards the lock, and the 'oii'tcr face of sa id link will engage with and move upon the flange 40* of the lock until lthe cross piece 4l* at the lower end of the link Q2 engage-i with the notch in said lock and rotatesv the same upwardly until the shoulder 32n thereon engages with the outer cud 33 of the locking lever 35'. Thislatter uio-rement will take place simultaneously with the return of the lock ou the oppo-:te sid-` of the car in its normal position. so that hott. s'ulc.- of the car will be locked at the sau-ic moment against a duniping movement thereof.

It- ""f bc noted thai'l when the canbody is beiiigjiighted. tlzc .inch ou thai .eide of the car will more upaireily with the piston rod. and will carry wiii: it the lcv 35: after moving in nvardl v,;|lie predri led distance. the cani iat-e of the lan-"l- .i .il come in Vthat as the righting movement continues,

when lilik 22- engages the notch in the disk 29, and exercises a pull thereon, the end 334 of the lever 35 will engage against the shoulder 32* and 'revent further upward movement of the iink 22, thereby locking the car body on that. side. In the description above given. it is stated that. when the car is heiiiggl dumped, the lever 35 will be lifted out of engagement with the disk 29 by.nieans of the latch 4G, and that the latter will beginn a side thrust at a redetermilled ont, thereby releasing tie saine from said lever. It is clear that it isnot. necessary to release` the lever on the dumping side of the car for the reason that the return of the latch to nornial positionftakes place before the riglitiir; of the car has been conilnenced, and therefore said lever would be in proper position to lock said disk '29 whenever such lockingr becomes necessary. The releasing: of the lever from the latch becoincs important only in case of the lever located on the side of the car upon which the righting.r force is exerted; and inasmuch as the mechanism on one side of the car may be used for dumping on one occasion and for righting on another occasiointhelatch should be so constructed that it will be released at the saine time. no matter whether the piston to which the latch is connected is at that instant rightingor dumping said car. Accordingly I have shown the latch of the saine construction on both sides of, the cai" and adapted to operate in the same manner.

It is apparent that vto rightthe car, the

notch l-l ou the plate. 11. whereas in dumpinff the car the link construction will engage with the lower notch on said plate.

(hir improved locking construction is automatic in its operation, and requires no attention to keep the saine in order; with the methods of locking:- in common use. the unlocking;r of the car oodics to dump the same. unil the lockiiw again when the same nrc lighted. would require a great deal of time and labor.4

Our construction is much more economical. is highly etlicient and dispenses with all the labor necessary to lock and unlock dumping cars as the .saine are found in coinmon use: the engineer of a train of loaded cars. seated in his cab, applies the air to the cylinders b v one movement of a lever. select.- ing the side of the cnr to which the power is to be applied. and the operation of the pistou to dump the car also causes the unlocking thereof. whereupon the same is immediately free to be dumped. As soon as. the

cars are dumped the air is cut o and the pistons are retracted to their normal position, thereby returning the members for manipulating the locking lever to their normal positions. Now to right. the car, the en gineor operates another levei` which will admit air into the c 'linders on the opposite sides of the ears` v: iereupcn the pistons will travel upwardly and cause the car body to resume its no1-mal position, the lockingdevices being returned to their normal locking 'ositions by the links depending from the car liody. Therefore, every operation of the car is controlled by the enoineer in his cab at the end of the train, and no personal attentionV to the manipulation of the locking devices is required.

Te do notmean to restrict onrselvesto a construction which is operated by an engineer in-his cab, ias-noted, but contem late improvements ivhich may be manipu ated by an operator at. any particular car, so that one. cai' may be dumped to the exclusion of all others.
